"I am Alastor. The weak shall give their heart and swear their eternal loyalty to me."

Alastor attacked Dante. The door had nothing to do with it. Alastor just happened to be lodhed in it.

​Dante was drawing power from Rebellion. He needs a a Devil Arm in 3 to DT. Rebellion was in his possession, and awakened. He uses it like a catalyst. It's the same principle behind using Sword Pierce and Round Trip but having DT still active.

Yamato was broken and inactive, Nero fixed it. We seen his DT being stimulated by Yamato but it didn't activate because it wasn't in his posession. This is the same reasoning behind Nero being unable to activate DT when someone else has claimed ownership of Yamato.
